The two largest seas in the world, ranked by surface area, are the Philippine Sea and the Coral Sea.
Here's a breakdown:
- Philippine Sea: This sea covers approximately 5.695 million square kilometers (2.199 million square miles).
- Coral Sea: The Coral Sea has an area of roughly 4.791 million square kilometers (1.850 million square miles).
It's important to note that the term "sea" can sometimes be ambiguous, and these rankings refer to seas that are typically defined as large marine areas bordering continents or larger ocean basins.
